Technical Field

[0001] This utility model relates to the field of lithium battery production, and more specifically, to a detachable composite insulation structure for lithium battery crucibles. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. With the development of science and technology, lithium-ion batteries have become the mainstream technology.

[0003] A search revealed that Chinese patent CN215955366U discloses "a low-temperature environment insulation structure for a lithium battery pack, relating to the field of related structural technology for lithium batteries. It includes a housing, within which a lithium battery pack and a heating device are disposed. The lithium battery pack is wrapped with an insulation layer, and the heating device is disposed beside the insulation layer. The heating device includes a mounting frame, with conductive frames disposed on the upper and lower sides inside the mounting frame. The conductive frames are connected to electrical wires, and conductive tubes are disposed at equal intervals inside the conductive frames. The conductive tubes are electrically connected to the conductive frames. An electric heating tube is disposed inside the conductive frame, and conductive heads are disposed at both ends of the electric heating tube, with the conductive heads movably sleeved within the conductive tubes. The beneficial effect of this low-temperature environment insulation structure is that by providing an insulation layer and a heating device, it achieves the purpose of insulation and heating of the lithium battery pack, allowing the lithium battery pack to operate normally in low-temperature environments and reducing dependence on the external environment." However, it still has the following drawbacks:

[0004] (1) The current lithium battery insulation structure has low overall installability when used, making it inconvenient to quickly install and fix the insulation material, thus reducing the overall usability and making it inconvenient to use quickly.

[0005] (2) The current lithium battery insulation structure has low connectivity with the outside when in use and lacks a good hiding and fixing measure, making it difficult to be tightly fixed with the external structure, thus reducing the overall usability.

[0006] Therefore, we made improvements and proposed a detachable composite insulation structure for lithium battery crucibles. Utility Model Content

The installation insulation component includes a slot 405 opened on the top surface of the base 1, and an insulation plate 407 is connected inside the slot 405. A top plate 401 is movably connected to the top of the base 1, and the insulation plate 407 insulates the interior of the base 1. The adjustment and fixing component includes a movable opening 501 opened at the bottom of the base 1, and a movable block 505 is movably connected inside the movable opening 501. A screw hole 506 is opened on the surface of the movable block 505, and the base 1 is fixed by the movable block 505.

[0035] like Figure 1 As shown, the base 1 has a second mounting block 403 fixedly connected to the four sides of its surface, and the top plate 401 has a first mounting block 402 fixedly connected to the four sides of its top. The connection between the top plate 401 and the base 1 is increased by the first mounting block 402 and the second mounting block 403.

[0036] like Figure 1 and Figure 4 As shown, the first mounting block 402 and the second mounting block 403 have mounting holes 404 inside, and the first magnetic block 406 is embedded and connected to the bottom of the slot 405. The mounting holes 404 increase the tightness of the connection.
